JAR-LIFTER.

Specification of Letters Patent. Pate te July 27, 1920,

Application filed November 25, 1919. Serial No. 340,621.

To all whom it may concern:

is it known that I, ALBERT K. SHEPPARD,

Port Moody, Province of British (lolumbia, Dominion of Canada, have invented new and useful Improvements in Jar- Lifters, of which the following is a specification.

This invention comprehends the provision of a simple, satisfactory and eflicient device for the handling of hot fruit jars or the like, and embodies among other features a pair of gripping elements which can be conveniently opened or separated, and when released subsequently is moved into gripping relation through the instrumentality of a spring.

The nature and advantages of the invention will be better undcrstood'when thefollowing detail description is read in connecsimilar parts in the several views and wherein:

Figure 1 is a side elevation of the device showing the normal position of parts.

Fig. 2 is a similar View showing the clamping elements separated, or in opened position.

Fig. 3 is an edge elevation.

Fig. l is perspective view of the handle.

Fi 5 is a similar view of one of the clamping elements.

Fig. 6 is a transverse sectional view through the connection between the handle and sliding frame.

The device forming the subject matter of my invention includes a handle 10 from which projects a rod 11 the lower end of the latter having associated therewith, arms 12 which project from the opposite sides of the rod 11 in divergent relation. The terminals 13 of said arms, are however, bent to lie substantially in parallel planes for the purpose to be hereinafter described. Sleeves 1 1 are also carried by the rod 11 and arranged at opposite sides of the latter, the sleeve however being disposed substantially at right angles to the arms 12. In other words, the sleeves 14 project from the sides of the rod 11, opposite the sides from which the arms 12 extend. A pair of spaced parallel bars 15 are arranged at opposite sides of the rod 11 and slide through the sleeves 141-, the latter servingto guide the bars 15 in their adjustment. The upper ends of the bars 15 are connected by means of a linger engaging element 16, which extends across the ends of the barand is provided with a central opening for. the reception of the rod 11. The finger engaging element 16 is of course slidably mounted upon the rod 11. terminate to provide eyes 17 which are connected by means of a rivet or other suitable fastening cle1nent'18. The coiled spring 19 encircles the rod 11 and hasone end bearing against the handle 10 and its opposite end bearing against the fingerengaging element 16, this spring serving a purpose which will .be presently set forth.

The clamping jaws or elements 20 are identical in construction, each being formed from a single length of wire or other suitable material, and bent at an appropriate point in its length'to provide an intermediate eye21 and oppositely curved extremities 22 and 23 respectively. :The extremity 22 is comparatively short with respect to the extremity 23, the corresponding extremities 23 of the respective clamping jaws being bent toward each other to provide an angularly disposed curved gripping portion 2a. The intermediate eyes 21 of said jaws are disposed side by side to receive the rivet 18, the latter constituting a pivot upon which the clamping jaws are actuated.

The curved portions 22 of the clamping jaws project above thepivot 18 and are oppositely disposed relatively, each extremity 22 terminating to provide an eye 25 disposed at a right angle to the intermediate eye 21, the eye 25 receiving the adjacent arm 12, of the rod 11 upon which it is slidably fitted.

n practice, assuming the parts are nor mally disposed in a manner illustrated in Fig. 1, and use of the device is desired, the handle 10 is placed in the palm of the hand,

and the fingers of the user engaged beneath the element 16. By closing the hand in which the device is held,th'e parallel bars 15 are moved toward the handle 10 through the sleeves 1 1, during which movement, the pivot 18 is removed into close proximity to the adjacent end of the rod 11. Consequently, the eyes 25 slide upon he diver-gently disposed arms 12 with the resultant opening of the clamping jaws 20. The terminals 13 of the arms 12 are so disposed as to prevent casual separation'of the eyes 25 as "will be appreciated. WVith the adjustment of parts in the manner described, the spring 19 is compressed and placed under tension as clearly shown in Fig. 2, so that when finger engaging element 16 is released, the spring functions to move the jaw 20 into a gripping relation. 'lVhen the jaws are moved into engagement with the jar or other receptacle to be carried, the spring 19 holds the jaws in effective engagement with the receptacle so that there is little possibility of the jar falling from the device while being carried thereby. The construction of the component parts assures positiveness in the operation of the device, which in addition to being simple in construction can be conveniently manipulated for the purpose intended.

'While I have shown and described what I consider the preferred embodiment of the invention I desire to have it understood that I do not limit myself in the detail construction shown and that such changes may be resorted to when desired as fall within the scope of what is claimed.

Having thus described my invention what arms projecting from said rod, eyes formed on the adjacent ends of said jaws, and slidably fitted on saidarms whereby said jaws are opened and closed by movement of said frame in opposite directions, and coiled springs interposed between saidhandle and fin er engaging element and encircling said rod for the purpose specified.

A jar lifter comprising a handle including a rod, 21 frame slidably mounted on said rod, a pair of clamping jaws, each of said jaws being formed at a point of plane with an eye, a pivot pin passed through the eye in thelower part of the frame whereby the jaws are pivoted upon the frame, and finger engaging elements forming part of the frame, 'and a connection between said rod and the adjacent ends of the jaws whereby the latter are opened upon movement of the frame by the finger engaging elements, and yieldable means operating the reversal movement of said parts upon release of said finger engaging elements.

8. A jarlifter comprising a handle including a rod, a frame including a finger engaging element, and spaced parallel bars arranged at opposite sides of the rod, a member carried by the rod and having spaced bores to slidably receive the bars of the frame, a pair of clamping jaws pivotally mounted upon the lower end of the frame, a

connection between said rods and the adjacent ends of the jaws whereby thelatter are 7 opened upon movement of the frame by said finger engaging element, and yieldable means operatlng to reverse the movements of said parts upon the release of said finger engaging elements.

. In testimony whereof I afiix my signature.

ALBERT KENNETH SHEPPARD.
